Referring to the drawings-alt designates the frame oi the nistol having :1- suitable handle 2, e cylindrical extension 3 having a slot at therein and with an extension 5 forminga chamber 6. i t itliin the handle 2 is the niegzisino chamber '3', which extends upwardly tlirougi the frame 1 and the upper end of which chamber is open for the insertion of the cartridges and for the discharge of the shells. The lower encl of the chamber is closed in o suitable manner, as here shown, by means of a plate 8 W'lllCll may be secured in position in only desired Way, i Within the magazine chamber '5 is sitiistetl a spring 9 of any snitslole form, and which, as here shown, osers againstthe piste 8 end resiliently supports the cap or follower ll), which is thus inoveloly mounted; in the magazine chamber 7. The said cap may be of any (lesirerl construction, but, as here shown, the upper face thereof is curved as at Al to suitably receive and support 2 cartridge and the said cap is provided with depending arms 1%, so that the some bear against the Wells of tile iniigeziine chamber 7, whereby the clip is properly guided in its movement and helcl in proper position at all times. Upon each side of the chamber 7 and at the rear end thereof, 1 proviiie the grooves 13 which, 91S will be more clearly seen from Fig. 2, are Wider at the lower portion then at the upper portion, 1 preferably provide that one Wall of each groove is corresponding-iv curved as at 14:, st 51 point adjecent that at which the cartridge, to be tired, is situated, in order that the grooves 13 at this firing point or slightly above the some, will lie of sufficient Width to engage and closely emlorecetlie lieeils tliecsrtridge lincl so positively hold the some in proper position, since it will lie onclerstoocl the sold grooves are provided to receive the needs of the onrl guide in their movement, and the cartridges which are at the lowermost portion or the magazine chamber may essoine any suitable position, but when they elevate-cl and as each is brought into the firing position, it is necessary that the same be held in suitable position to enter the barrel for firing, and also held when the barrel moves forwardly again, so that the fired shell will be in position to be properly engaged by the ejector, and it is for this reason that the said grooves 13 are narrowed at this portion of the magazine chamber 7. By making the grooves 13 wider at the lower portion, binding of the cartridges is prevented, as they are free to move upwardly with the follower.

Movably mounted in the frame 1, and in.

the cylindrical extensions .3, is the movable barrel 15, thesame being of any suitable length, and having a lug 16- projecting downwardly therefrom with which the trigger 17 is pivotally connected, said lug 16 being movable in the slot 4 of'the cylindrical extension 3, so that the said barrel will always be properly guided in its longitudinal movement.

Suitably connectedv with the barrel, as here shown, through the medium of the lug 16, is the tube 18, which is adapted to receive a spring 19, a portion of which is also situated in the recess 20 in the frame 1, said spring 19 serving as the barrel and trigger return spring and holding these parts in normal position. The inner end of the barrel is provided on its lower outer face with an incline or cam 21, and the lower wall of the bore is also slightly inclined at 22, thus serving to properly engage and guide a cartridge into its position within the barrel, when the latter is retracted, and to prevent any passing or jamming thereof. The inner end of the barrel is provided with a nose 23 in order that when the barrel is retracted and is in firing position, the said nose is seated within the'narrow cutaway portion or recess 24, of the frame 1, so that. solid metal is around the barrel during the act of firing. Suitably secured to, or carried by," the barrel 15 is a cooking pawl 25. As here shown, the said cocking pawl is provided with a key 26 forming shoulders 27, which key is seated in a recess 28 formed in the side of the barrel with a suitable portion of the pawl 25 seated in the slot 29 formed in the barrel, which communicates with the recess 28, and which forms shoulders 30, with which ngage the shoulders 27 of the key, whereby it will be understood that the said cocking pawl, whenin position in the frame 1, will be securely and firmly held with respect to the barrel 15 and will be movable therewith.

31 designates a sear on the cooking pawl which is adapted to engage the firing hammer and to release the same, as will be hereinafter described, it being understood that the said cocking pawl is of suitable spring material or is spring actuated, if desired.

32 designates a firing pin which is movably mounted in the chamber 6, and which may be of any suitable construction, and, as here shown, is provided with a pin 33, which is adapted to pass through the opening 34, in the frame between the magazine chamber 7 and the firing pin chamber 6, in order to fire the cartridge. The said firing pin 32, as here shown, is held in place by a cap 34,'which is provided with a squared opening 35 in which is movable the squared arm 36 of the firing pin, while bearing against the pin, for holding the same in normal position and: returning. the same thereto, is the spring 37. The firing pin is adapted to be engaged by, and released from, the cocking pawl at the proper time, and suitable means are provided for this purpose. provided with a head 38, with which the sear 31 of the cocking pawl engages, this construction being best seen in Fig. 9 and the end of said cocking pawl 25 being situated, and movable in the cutaway portion or recesses 39', in the side of the frame 1. The inner wall of such recess at or near the fir- As here shown, the firing pin is ing point is providedwith an inclined face 40, with which the'end of the cocking'pawl 25 engages, when it has moved a suitable distance-for this purpose and by the continued rearward movement of the barrel 15, the sear 31 will ride out upon the in clined face into the position seen in Fig. 10, and will release the firing pin, as will be evident, whereupon the spring 37 will return the same to normal position and will fire the cartridge.

41 designates a plate which is adapted to close the recesses 39 in the said frame, and is also adapted to enter a notch 42 formed in the cap 34, so that said plate 41 serves to lock the cap and the coacting parts in proper position. Upon the opposite side of the frame 1 is a recess or cut away portion 43, and ate suitable point in said recess is pivotally mounted the ejector 44. As here shown, the ejector is pivoted at 45 upon a suitable part of the frame 1, and is provided at one end with the inclined or cam face 46, and also at a suitable point, in its extent, with a second cam face or incline 47.

The ejector is formed with an outwardly extending lug 48, having a head 49, which head and lug are movable through a recess 50 in the frame 1, and the normal position of said head 49 being above the top of the frame 1. The ejector 44 is also provided with a tooth or car 51, which is adapted to engage with thecartridge or'shell, as will bedescribed. Mounted upon the barrel 15 is a stud or pin 52, which is seated at a suitable point on the barrel with respect to the ejector 44, in order that the said pin 52 in its normal position will be in engagement with the inclined face 46 thereof, in order to normally hold the ejector in elevated poa ll it 6, I have shown the position of the ear 51 of the ejector when the barrel is in its forward position, and with the said car 551 slightly above the cartridge, but as the moves rearwardly, the said ejector ear 51 will be moved outwardly and downwardly, and in '8 l. have, shown the posit the car 51 passing thecartridge, in the firing position of the barrel, the said car 51 will be slightly bethe cartridge, as seen in Fig, 8. After the firing has occurred the barrel starts to move outwardly, the said pin 52 is so situated with respect to the curved face 530: the barrel, that the ejector will first move to a position beneath the cartridge when it is released from engagement with the inclined face of the barrel, and .by the continued forward movement of the barrel, the pin 52 will release the can face 4:7 and finally engage with, and ride upon, the cam face 46, elevating the ear 51, and ejecting the shell through the opening in the top of the frame.

I have provided a safety lock or closure for the pistol, and, as here shown, I provide a slide 5%, which enters suitable grooves or recesses in the top of the frame 1, which slide carries a plate 55 having a finger-piece so thereon and having a suitable slot 57, which forms a 5 )ring tongue 58, it being understood that w en the arts are as seen in Figs. 1 to 15, that the sa d plate 55Vis positioned above the opening of the magazine chamber 7,completely closing the same, and that the end of the ejector is in the slot 57, with the spring tongue 58 engagin with the head 49 of the ejector, so that ownward movement of the same is prevented and the parts are locked in position, and the trigger and barrel can not move.

The operation of the device is as follows :The safety lockingplate is moved from its position above the opening to the magazine chamber 7, and cartridges 59 are inserted in the opening, being pressed or pushed past the ear 51 of the ejector, thus depressing the follower 10 and compressing the spring 9, and the desired number of cartridges an thus be inserted, said ear 51 holding the said cartridges within the chamher 7 against the tension of the spring As will be understood, the heads of the cartridges are seated within the grooves 13, so that they will be positively guided in their movement and held in their proper position as previously explained, as each cartridge reaches the firing position, it being understood that the barrel and the firing pin with their coacting parts are in the position seen in Figs. 1 and 9 during the act of loading. in order to fire the pistol, by pulling on the trigger 17, the barrel 15 is moved rearwardly, in the cylinder 3 and frame 1, and in its movement it will receive the topmost cartridge which is in the firing position, as best seen in Fig. 2. As the barrel moves rearwardly, will be understood that the cocking pawl 25, which is'in engagement with the firing pin 32, will move said firing pin rearwardly nntil the proper portion of the cocking pawl 25 comes into en agementwith the inclined wall d0 of the frame, at which time the end of the said cocking pawl 25 is moved outwardly into the position seen in Fig. 10, releasing the firing pin 3:2, at

which time the spring 37 returns the same forwardly to its normal position, causing the pin 33 to strike the cartridge and discharge the same. When the barrel 15 moves rearwardly, it will be understood that the pin 52 is removed from contact with the inclined face &6 of the ejector at, and it will then engage with the inclined face a? thereon. This depresses the ear 51 carried by the ejector and lowers the same to a position in which it can pass beneath the shell of the tired cartridge after the barrel 15 moves forwardly again, it being understood, as previously stated, that the inclined face of the barrel forces the free end of the ejector outwardly into the position seen in l ig. 10 when the said barrel 15 is thrown backward. l/Vhen the barrel 15 moves forwardly again, the ear 51 of the ejector moves over to a position beneath the shell, and when the pin 52 again comes in contact with the inclined face 46 of the ejector, it elevates the free end thereof and the ear 51 will automaticall eject tl1e discharged shell 59 through the opening in the top of the frame 1. After the cartridge has been fired and the shell ejected, the spring 9 will elevate the follower 10, raising the cartridges carried thereby, and lacing another cartrid e in the firing position, it being understood as previously stated, that the cartridges will be positively guided by the grooves 13 in which the heads of the cartridge are seated, and that by reason of the narrowing of the said grooves at a point adjacent to and at the firing point, the said cartridges will be positively heldv in proper position to enter the bore of the barrel, while the inclined faces on the inner end of the barrel 15 will prevent jamming of the cartridge and will assist in properly directlit) ing and guiding the cartridge into. the barrel. v
